Use Superset MCP health, instance, list, detail, schema, and chart-type discovery tools. Use only for MCP tool workflows; do not use for direct API work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# preset-mcp-discovery Use for MCP metadata discovery that does not require result data or persistent changes. ## Always - On the Preset gateway, start with `preset-mcp-gateway` (`list_workspaces`, workspace selection). The list/detail tools below are workspace tools called through `call_tool`. - Use the single narrowest tool that answers the question; discovery calls are for missing IDs, names, or schemas — not a mandatory ladder. - Do not repeat an identical list call; reuse earlier results. Following pagination or refining a search filter when the target was not in the returned page is fine. - When a call fails on filter, sort, pagination, or request wrapper fields, fix it against the live tool schema rather than guessing again. - Do not expose hidden dataset, database, schema, or SQL details after permission errors. ## Decision Rules - Use `health_check` and `get_instance_info` only when the user asks about service health or the workspace itself. - Use `list_*` tools once to find IDs when the identifier is missing; pick a `page_size` that covers the request in one call. - Use `get_*_info` for details of a specific known object. …

How to install
mdr add preset-io/agent-skills/preset-mcp-discovery@sha256:a7696f5417284b48The line at the top of this page pins the label git:20261007.d55e493, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
